I had a a crappy 8 page adsense site from years ago get hit by, what i'm pretty sure, was the penguin update. It was making around 25-30 GBP per month. Not completely surprised it got hit as it was a really ****ty site. It was my first proper one and I always intended to do it up and turn it into a really good authority content site eventually as it was my first ever site.
I'm fairly sure it was a penguin hit because of the date all my adsense earnings completely vanished. I was expecting a panda hit if anything. From my limited knowledge of penguin sites, its usually caused by keyword spamming which I don't remember doing when I made it.
Penguin is supposed to be an algorythmic thing so I should supposedly be able to get it back in the high Google rankings by making the appropriate changes. I had a load of even more shockingly bad quality sites from when I first started learning about Google originally but none of those have been hit.
Let's treat it as a case study, how to get your site out of the penguin. The link to it is in my signature.
I'm doing this because I thought it might be valuable for people who have experienced the same kinds of problems. Please don't be dickheads and do nasty stuff to my website.
I'm really busy with other projects at the moment but will try to make the necessary changes when I can. What kinds of things do you guys suggest I change to get it back into the SERPS? I will try most reasonable suggestions.
Hope this might help others learn how to correct their mistakes.
